Unable to change datatype on SQL Server 2008

Has anyone come across this.

I have a table on a SQL Server 2008 database with a column of varchar(50).

In Toad in an Object Browser (I think that is what it is called)
window I right click on the table and select Alter Table.

The alter table screen opens up and I select the column and change varchar(50)
to nvarchar(50).

Click on Ok

The window flashes, moves to the ‘Generating script’ window

Leaves me with a – No changes detected in the SQL Script window.

I have tried this on the same table/column on a SQL Server 2005 database and it
works ok.

Is this not possible in 2008?

Hi Jon,

This works fine for me on TSS 5.5 as well as on 5.6 on my test table. Please
provide create script for your table so we can take a look.

Thanks for the response but I have upgraded to 5.6 now and it works.
